Thanks a lot for researching this. I have commited this to the default
config file though there is some weirdness in using the boundary chars
to delimit the match (e.g. "else if" does not get coloured properly
unless you double the space). I also added $ (i.e. eol) to the list of
delimiters.

You could already do this with -s none (or -s hjklhjkl really), but I
agree -S seems cleaner. Thanks again and commited.

Yeah, me too. As agreed, mine will follow more or less the emacs
defaults. It was difficult to remove many keybindings and adding a
condition was maybe a hacky solution. I have commited my attempt as
config.control_only.h Please feel free to try and provide feedback.
Some differences from the emacs default or the default config:
- ^U works as it should.
- ^C kills the next word (former META-D). Sorry, I seem to use this one a lot.
- ^K, ^W, ^H and ^D complete your killing family as usual. I don't
know how much you guys use these.
- ^A / ^E go to bol / eol or, if already there, move by one full page.
I find this weirdly comfortable.
- ^S / ^R as for a search term or, if there is any selection (e.g.
right a search match), search for the next occurrence of the previous
search.
- ^@ sets (the one) mark
- ^O goes to the other side of the selection, or to the mark if there
is no selection.
- ^T prompts you for a line to go to.
- ^[ (also Esc) prompts you for syntax, but it may as well be a
command line writing directly to the pipe. It has a slight lag while
attempting to read a META sequence. NCurses fault, not mine. Will try
to solve.
- ^X saves or quits, ^Q quits without asking (!!), ^] extends the
selection as the former ^X.
- Sadly, there is no easy way to move word-by-word: Shift+Left/Right
is the current only binding. You can still kill words left and right
with ^W/^C.
- Sadly, there is no immediate way to copy to the clipboard: it is
either cut and paste (e.g. ^W^Y) or move your hand and press INS.
I do not intend to keep two default config files in the repo except
for tests and such, so try and report any weirdness and we can make
this the default; unless we like pancake's version more, of course. We
can have a wiki page, a separate repo or something for alternative
configurations.

As I already said, I have mixed feelings about modality. In case we go
modal, we'd probably use something akin to vi's command mode bindings
I guess. Let's hear some opinions before acting.
A tad unrelated, but not really... I was quite sure about using
keyboard positioned bindings before (be them hjkl, ijkl, the wordstar
thingy or even wasd as it has been suggested). However, a lot of
suckless software users seem to have a non-qwerty keyboard layout.

He reached to me this morning, ought to have the repo in place tonight.

I'm a sucker for pretty colors, but I understand not everyone likes
them that much. I'll add a few #ifs to make them optional later today
or tomorrow. Incidentally, it is now very easy to remove current line
highlighting and the weird chars painted in place of ' ' and '\t' by
editing config.h. Thanks to pancake again.
Best regards,
Rafa.
